I purchased a system several months ago along with the "complete installation kit".  This "kit" is NOT complete.  The kit does NOT include the extra filter in the system.  There are lines and fittings missing.  Very disappointing in that the system is advertised as "complete".  
Thankfully the extremely helpful & professional service department helped me and shipped an extra part that completed the install.  They helped me install the system without leaks after months of frustration and leaking issues.
